Major traffic disruption is expected in Glasgow city centre on Saturday as the annual Orange Order parade takes place.

Many city centre roads will be closed as around 4500 musicians and supporters take part in the walk, watched by an estimated 4000 spectators.

Police have warned those attending against public drinking during the annual County Grand Orange Order parade and said officers "will not tolerate sectarian or antisocial behaviour".

People coming into Glasgow in the morning and early afternoon were advised to adjust their travel plans.

While the main procession is not due to leave George Square until 10.30am, there will be a number of feeder marches, each beginning at around 8am in various districts of the city.

Participants will then assemble in the Square at around 10am for a short service at the Cenotaph.

From there, the parade will proceed to Glasgow Green where a rally will be held. This is due to finish at 1.45pm, when the bands return to their home districts.

The roads most affected by disruptions will be Blythswood Square, West George Street, George Square, George Street, High Street, the Saltmarket and Glasgow Green.

There will also be numerous roads closures during the day around the city, particularly on side roads leading to the route of the parade. Full details can be found on the Glasgow City Council website.

The full parade from George Square to Glasgow Green will take two hours to complete.

People driving in and around the city centre are advised to follow the advice and directions given by police officers and stewards, and to leave extra time for their journeys.

Superintendent Alan Murray, in charge of policing the event, said: "My priority is public safety. That means the safety of everyone - those taking part in the parade and the public in general.

"As is the case every year, thousands of people will be involved in the parade so I would advise anyone coming into the city during the day to plan their travel.

"Although we have been working closely with event organisers and the local authority to minimise disruption to road users and the local community, it is inevitable that there will be delays.

"As everyone should be aware by now, drinking alcohol in the street or in any public place is illegal and officers will be ensuring that people comply with this legislation.

"Previous experience shows that it is the unwelcome minority who use the event to drink too much and cause offence, however, be assured we will not tolerate and sectarian or antisocial behaviour."

Jim McHarg, Grand Master of the Grand Orange Lodge of Scotland, said: "Last Saturday, over 4000 Orangemen comprising the 73 lodges and 45 bands from Edinburgh and the east of Scotland rallied at Prestonpans.

"The music and pageantry was viewed by hundreds of spectators and was entirely trouble-free.

"It is my hope that this Saturday's Orange celebrations in Glasgow (151 lodges, 63 bands) and Saltcoats (74 lodges, 32 bands) will also be colourful spectacles that will not be marred by any untoward incidents or misbehaviour."
